Hello Vishnuvarthan,

I am just checking if you got this worked out or you still require any assistance or clarification on the matter.

Hello Vishnuvarthan,

I have been looking into your code, but I am not able to conclude what can cause this without an isolated sample project, where your issue is reproduced so, could you please send us such sample project, so we can investigate it further for you.

Looking forward for your reply.

Hi Stefan,

Thanks for your sample application, it is working fine, i didn't pass the data XmlDataProvider through xaml, Actuall i am using MVVM pattern, i tried your sample it's not working, could you please provide MVVM pattern for the same.

I have use below coding,

ViewModel.cs

public XmlDataProvider PrototypeProvider
{
get { return _prototypeProvider; }
set
{
_prototypeProvider = value;
// Call OnPropertyChanged whenever the property is updated
OnPropertyChanged("PrototypeProvider");
}
}

public void prototypeMethodQuery(string Prop)

{
ReportType = Prop;

string PrototypeXmlString = null;
//PipelineBrowserServiceClient ws = _pipeDAL.GetPipleineServiceClient();

//string[] StratsList = ws.selectAllStrat();
//string[] SummaryList = ws.selectAllSummarization();

try
{
PrototypeProvider = null;
IsEnableApply = false;
if (ReportName != null && Prop == "Strats")
{
string stratOptions = null;
stratOptions = _pipeDAL.GetStratCategory(ReportName, SelectorConditions);
PrototypeXmlString = stratOptions;
}

if (ReportName != null && Prop == "Summaries")
{
string summaryOptions = null;
summaryOptions = _pipeDAL.GetSummaryCategory(ReportName, SelectorConditions);
PrototypeXmlString = summaryOptions;
}

if (PrototypeXmlString != null && PrototypeXmlString != "")
{
// prepare xml
XmlDocument doc = new XmlDocument();
doc.LoadXml(PrototypeXmlString);
if (PrototypeProvider == null)
PrototypeProvider = new XmlDataProvider();

if (PrototypeProvider != null)
{

PrototypeProvider.Document = doc;
PrototypeProvider.XPath = "/Results";

PrototypeProvider.IsInitialLoadEnabled = true;
PrototypeProvider.IsAsynchronous = false;
//PrototypeProvider.DeferRefresh();
PrototypeProvider.Refresh();
}
}
else
{
PrototypeProvider = null; // PipelineSummaryList;
}
}
catch (Exception ex)
{
Logger.Write(ex.StackTrace);
}
}

Please assist.
